mxSetData (C and Fortran) - Set pointer to data

C Syntax

#include "matrix.h"
void mxSetData(mxArray *pm, void *pr);

Fortran Syntax

mxSetData(pm, pr)
mwPointer pm, pr

Arguments

pm

Pointer to an mxArray

pr

Pointer to an array. Each element in the array contains the real component of a value. The array must be in dynamic memory; call mxCalloc to allocate this memory.

Description

mxSetData is similar to mxSetPr, except that in C, its second argument is a void *. Use this on numeric arrays with contents other than double.

This function does not free any memory allocated for existing data that it displaces. To free existing memory, call mxFree on the pointer returned by mxGetData before you call mxSetData.
